To all lwhom it may concern.'

Be it known that I, WILLIAM BARTHOLO- Mnw, citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Treadle Mechanisms, of which the following is a specication, reference being had therein to the accompanying drawing.

This invention relates to a treadle mechanism, and particularly to a construction adapted to operate independently controlled active elements of a machine by means of a single treadle capable of movement in a plurality of planes.

The invention has for an object to provide a main treadle adapted for oscillation and for rotative movement about its longitudinal axis in combination with an4 auxiliary lever mounted upon an independent support and slidingly connected for opera tion by one of the treadle movements.

A further object of the invention is to provide a novel and improved pivotal mounting for the treadle and the connection therewith of an auxiliary lever so that the treadle is capable of oscillation in a vertical plane to actuate said auxiliary lever, and also of rotative movement about its longitudinal axis for independently controlling another mechanism therefrom.

Other and further objects and advantages of the invention will be hereinafter fully set forth and the novel features thereof defined by the appended claims.

In the drawings :wFigure 1 is an elevation showing the invention applied with parts in section; Fig. 2 is a detail elevation showing the invention applied to a motor driven mechanism; Fig. 3 is a section on line 3h3, Fig. 1; Fig. 4 is a detail elevation of the treadle pivot; Fig. 5 is a detail section showing the pivotal connection with the actuating lever for the mechanism.

Like numerals refer to like parts in the several views of the drawings.

This invention is adapted for application to any mechanism, and particularly for the control of the driving device and the independent control of active elements of said mechanism, whether driven by belt or motor,

and is here shown in connection with an ironing machine only for the Apurpose of illustrating one application thereof.

Referring to the present application of the invention, the numeral 10 designates a standard of any desired character or conguration upon the base 11 on which bearing lugs 12 are mounted and between which lugs the treadle bearing 13 is disposed and suspended by a pivot 14 extending through the lugs. I/Vithin this bearing the treadle rod or bar 15 is mounted for rotative movement about its longitudinal axis and is held against longitudinal movement in its bearing by collars 16 at opposite sides thereof. The treadle 15 is provided with a foot piece 1.7 Vat itsl free end which extends at opposite sides thereof and is adjustable longitudinally thereon for the use of either foot of the operator so as to secure leverage for rotation of the treadle within its bearing when desired. This treadle is provided adjacent to the bearing with a crank arm 18 extended therefrom through aperture 19 into the standard 10. This crank arm is provided with a head`20 having a curved rocker face 21 from which the projection 22 extends through an aperture 23 in the lower end of the operating bar 24, this bar having adjacent to the aperture a curved rocker face 25 to engage the face 21. The projection 22 is pivotally mounted by pin 26 within the aperture so that in the rotative movement of the lever 18 the face 21 thereof rocks upon the face 25 of the bar 24 during the downward movement or pull. This bar 24 is pivotally connected at its upper end 27 with the shifting lever 28 which may be pivoted in any desired manner, for instance, by means of the cross arm 29 pivoted at 30 in the projection 31 at one side of the standard, and connected at its other end with any desired shifting mechanism as will be hereinafter described. Coperating with the treadle 15 is an auxiliary lever 32 controlled by the vertical movement of the treadle. This lever is mounted upon the'base 11 independent of the treadle by means of the pivoting lugs 33 between which the lever is disposed, and the outer end of the lever is provided with a pivoting eye 34 adapted to embrace a pin 35 which extends laterally from a sleeve 3G slidably mounted upon the treadle 15. ln the oscillation of the treadle this sleeve has a longitudinal reciprocation thereon owing to the different points of pivot between the parts. The inner end of the auxiliary lever is provided with a vertically disposed arm 37 having a socket 38 therein. r1`he arm 37 of the auxiliary lever is normally drawn toward the standard by means of the tension spring 39 connected to the arm at 40 and to the standard at 41 so as to normally raise the treadle to its highest position.

ln the present application of the invention it is shown in connection with an ironing machine having a power controlling and shifting mechanism, and the ironing rolls 42 and 43 thereof are adapted to be relatively separated by the operation of the auxiliary lever through the treadle. The specific construction shown raises and lowers the lower most roll 43 by means of the rod 44 which at its lower end 45 has a pivoted bearing in the socket 33 so that when the treadle is depressed the roll 43 is raised into contact with the roll 42. 1n the form of shifting mechanism shown in Fig. 1, the upper end of the lever 28 is connected with the slide bracket 46 mounted upon the shaft 47 normally held at one end of its travel by spring 4S. From this bracket a belt shifting arm 49 extends to the belt shifter 50 disposed adjacent the driving pulleys 51 and 52 which are at opposite sides of the loose pulley 53 on the shaft 47. This shifter is provided with belt loops extended in opposite directions therefrom to carry a direct and crossed belt. The shaft 47 is provided with a gear 54 meshing with a driving gear 55 on the shaft 5G for continuously rotating the upper roll, while the lower roll is driven from the shaft 5G in the usual manner by means of the inclosed gears at 57 which are shifted into and out of mesh by the movement of thelower roll. Then the lower roll is raised its gear meshes with the coperating gear of the upper roll, as shown, and both rolls are thus positively driven. If it be desired to reverse the direction of drive the belt upon the driving pulley 52 is shifted to loose pulley 53 which carries the reverse drive belt from this loose pulley to the driving pulley 51 thus reversing the direction of rotation of the rolls. lllhen the side pressure upon the treadle is released the shifter spring at once restores the belts to their initial position, as shown in Fig. 1 so that the rolls rotate in proper direction to avoid the unwinding of the clothing upon one thereof. The treadle foot piece may be adjusted longitudinally upon the treadle so as to be used by either foot of the operator, as indicated by dotted lines in Fig. 1.

In the application of the invention, as shown in Fig. 2, the slide bracket 4G is pivotally connected to the lever (57 which is provided with oppositely disposed contactarms 58 adapted to engage contacts 59 electrically connected with the driving motor 60 for controlling the direction Aof rotation thereof, while the current to the motor may be controlled through the switch 63. The shaft of' this motor is provided with the worm gear 61 adapted to mesh with the pinion G2 carried on the shaft 56 of the upper roll. Although the invention has been described in connection with an ironing machine and driving mechanism therefor, it is not confined to such use but is capable of application to any machine to which it may be adapted.

1n the operation of the invention it will be seen that a downward movement of the treadle controls the movement of the auxiliary lever to shift the independently con trolled active elements of a mechanism relative to each other and this may be effected without operation of the power controlling or shifting mechanism. After such depres sion the treadle may be partially rotated upon its pivot or axis for operating such controlling mechanism. It will also be apparent that by a proper pressure at one side of the axis of the treadle the power mechanism may be controlled without necessarily operating the auxiliary shifting lever. This mechanism is therefore adapted to control independently active elements of a machine by a treadle having a single foot piece and to start, stopy or reverse the power driving devices for parts of said mechanism by a movement of the treadle which may be independent of the control of the active elements of the auxiliary lever or effected subsequent thereto and after the treadle has reached the limit of its downward movement- Having described my invention and sct forth its merits, what 1 claim and desire to sceure by Letters Patent is 1.
